Definition of reverse osmosis. Reverse Osmosis (RO) process consists of generating an aqueous solution with a low salt content from another aqueous solution that has a high salt content, via a water-permeable membrane.. It is the technology used to produce desalinated water from seawater. Just as in MF and UF, the driving force for achieving the separation of the salt is caused by a difference ...
Get PriceReverse osmosis ( RO) is a water purification process that removes ions, unwanted molecules and larger particles from drinking water using a partially permeable membrane. As a result, the solute is kept on the membrane's pressurized side and the pure solvent is allowed to pass to the other side.
